quarterback

The quarterback (QB) is an offensive position in gridiron football. The quarterback typically lines up behind the center and receives the snap to start each play. The primary role is to advance the ball by passing or handing off to a running back, and to direct the offense on the field.

The quarterback must read the defense, diagnose coverages, and decide whether to throw, hand off, or run. They often call audibles at the line of scrimmage and coordinate with the offensive line, running backs, receivers, and tight ends. Success depends on timing, decision-making, and field vision.

Key skills include accuracy, arm strength, pocket presence, footwork, and leadership. Style varies: pocket passers rely on throws from a clean pocket, while dual-threat quarterbacks add running ability. A quarterback's performance is tracked by statistics such as passing yards, touchdowns, and interceptions.

The position exists in American football and Canadian football, with similar responsibilities but adapted for different rules and field dimensions. In the NFL, quarterbacks typically wear numbers from 1 to 19; college football allows a broader range.
